i have been trying to tune my os 55ax and for some reason i cant find that sweet spot the engine revs hard but when i try tuning it with the high speed needle it doesn’t really have a sweet spot what i mean is that when i have a reasonable tune, i can turn the high speed needle around about 3/4 each way and not hear a difference. it has a 12x7or 8 (got to check) prop on it. im starting to get worried because it has cut out two time in three flights with my paramount and it would have cut out on the third flight but i managed the throttle and tried to keep it going please tell me what the problem might
